Location

The furnace must be installed on a level surface, and as close to the center of the air distribution system as possible. See Table 3 for overall dimensions to determine the required clear- ances in hallways, doorways, stairs, etc. to allow the furnace to be moved to the installation point. The furnace must be installed so that all electri- cal components are protected from water.

Minimum clearances to combustible materials are listed in Table 4. Access for positioning and servicing must be considered when locating the unit. 24 inches is the minimum required clear- ance for servicing the unit. 30 inches is the minimum required clearance for positioning the unit. 36 inches is the recommended clearance from the front of the unit. Please note that a panel or door can be located such that the minimum clearance on the rating plate is satis- fied, but that panel or door must be removable and allow the appropriate clearance for your installation.

This furnace is certified for use on wood flooring. The furnace must be installed on a solid surface and must be level front to back and side to side. This furnace must not be installed directly on carpeting, tile, or any combustible material other than wood flooring.

DOWNFLOW WARNING (G6RL Models):

The design of the downflow furnace is certified for natural or propane gas and for installation on non-combustible flooring. A special combus- tible floor sub-base is required when installing on a combustible floor. Failure to install the sub- base may result in fire, property damage and personal injury. The special downflow sub-bases are factory supplied accessories, part numbers 902677 and 902974. When the furnace is in- stalled on a factory or site-built cased air condi- tioning coil, the sub-base is not necessary. However, the plenum attached to the coil casing must be installed such that its surfaces are at least 1" from combustible construction.

A gas-fired furnace installed in a residential garage must be installed so that the bottom of the furnace is located a minimum of 15" from the floor. The furnace must be located or protected to avoid physical damage by vehicles.

HORIZONTAL INSTALLATIONS

The G6RC model furnaces are approved for horizontal installation. Installation Kit #903568 is required for horizontal applications. Follow the installation instructions in the kit for proper conversion. NOTE: The G6RD and G6RL mod- els are NOT approved for horizontal installation.

SUPPLY AIR PLENUM INSTALLATION

A.Installation on a concrete slab - G6RL

1.Construct a hole in the floor per the dimensions in Figure 3.

2.Place the plenum and the furnace as shown in Figure 4.

B.Installation on a combustible floor - G6RL

1.Cut and frame the hole in the floor per the dimensions in Figure 5.

2.Place the sub-base for combustible floors over the hole with its duct collar extended downward. Attach the supply air plenum to the base in a manner which will ensure 1" clearancetotheflooringorothercombustible material. Place furnace on the combustible base as shown in Figure 6.

3.When the furnace is installed on a factory or site-built cased air conditioning coil, the sub-base is not necessary. However, the plenum attached to the coil casing must be installed such that its surfaces are at least 1" from combustible material.
